The biotite and/or amphibole will undergo hydrolysis to form clay, and oxidation to form iron oxides.

Weathering is a time period which describes the overall procedure via way of means of which rocks are damaged down on the Earth’s floor into things like sediments, clays, soils and materials which might be dissolved in water.
The procedure of weathering usually starts off evolved while the earth’s crust is uplifted via way of means of tectonic forces. After the bodily breakup and chemical decay of uncovered rocks via way of means of weathering, the loosened rock fragments and changes merchandise are over excited via the procedure of erosion.
Erosion is based on transporting dealers consisting of wind, rivers, ice, snow and downward motion of substances to hold weathered merchandise far away from the supply area.
